RE: [DUG]: Array of components

I think what you've got is a dynamic array. So you need to call SetLength(array,length) to initialise the array. You can avoid this by using a static array (one declared with [1..100]). The advantage of a static array is that it can be re-sized by another call to SetLength(array,length).

RE: Re: [DUG]: Array of components

This is inefficient because every time you call SetLength, it re-allocates the array in memory, then copies the contents from the old allocation to the new one. A better method is to initially declare the array big enough to fit what you expect to put into it. Before doing the insert, check

Let's just fix the actual bug (worry about efficiency later) DirMonArray[DmonCount - 1].Create(self); //= creation error here of course it will crash.. try DirMonArray[DmonCount - 1] := TDirMonitor.Create(self); -Original Message- From: Allan, Samuel [mailto:[EMAIL

RE: [DUG]: Array of components

Also. Uses Contnrs (TComponentList, or TObjectList) might be a little easier than managing an array, then you won't have any dimension issues to worry about -Original Message- From: Alistair George [mailto:[EMAIL PROTECTED] Sent: Monday, 31 March 2003 10:50 a.m. To: Multiple recipients

RE: RE: RE: Re: [DUG]: Array of components

Also, the array is of object references. So if you want to create a new object in the array you need to do it like: Array[x] := TMyObject.Create; :-) -Original Message- From: Kyley Harris [mailto:[EMAIL PROTECTED] Sent: Monday, 31 March 2003 11:38 a.m. To: Multiple recipients of list

Re[2]: [DUG]: Array of components

Wow, thanks all for that fine bunch of info. After scanning the internet the info on this subject is not great, so the groups knowledge here has been of very high standard! Any chance of an example of the correct way to use the Tcomponentlist? What I have done is: declare: var

RE: Re[2]: [DUG]: Array of components

Try if TDirMonitor(DirMonList.Items[Tval]).Directory = CurrDir then Exit; you probably need to cast the object to the correct type. Dave. -Original Message- From: Alistair George [mailto:[EMAIL PROTECTED] Sent: Monday, 31 March 2003 12:27 p.m. To: Multiple recipients of list delphi

[DUG]: Testing Installed components

Hi I'm having trouble figuring out how to debug a visual control at design time. I've created the source file VisualControl.pas and a new package dcontrols.dpk which I've compiled and installed on the component pallet. Now I want to catch the OnResizeEvent of my control at design time, when I drop

RE: RE: Re[2]: [DUG]: Array of components

Casting is good. You really want to subclass TComponentList. (it doesn't take long) ie. example TEditPanels = class(TComponentList) function GetItems(Index: Integer): TEditPanel; procedure SetItems(Index: Integer; const Value: TEditPanel); public function Add(AComponent:
